ROTARY IBAR-SCALPER.

Specification of Letters Patent.

Patented Sept. 2, 1913.

To all whom it may concern:

Be it known that we, CORNELIUS S. Vos BURGH and JOSEPH L. Gr. BLOUIN,both citizens of the United States, and residents of Waterbury, in thecounty of New Haven and State of Connecticut, have invented certain newand useful Improvements in Rotary Bar-Sealpers, of which the followingis a specification.

The object of the invention is to produce a machine of the characterdescribed having novelty and advantage, and more especially to improvethe process of scalping and reduce the expense of the process.

Referring to the drawings: Figure 1 is a plan view of the machine withthe top of the frame and the feed roll driving mechanism removed. Fig. 2is a side elevation of the same. Fig. 3 is a sectional view on the line3, 3, of Fig. 2.

This machine is designed for the purpose of clearing from the sides ofmetal bars the scale which is left on the bar after the preliminaryrolling operation has been com pleted.

a denotes the bed of the machine having the transversely arranged rolls6 forming a track on which the stock which is to be operated upon passesthrough the machine.

10, 20, denote opposed rotary cutter head disks, one being arranged inadvance of the other, and mounted on shaft 1, 2, supported in suitablebearings 3, 3 and 4, 4:. Projecting from the front face of each disk andarranged in a circular row near its edge are a series of operating tools5.

The bars which are to be operated upon, and one of which is indicated at1', are introduced edgewise, and one side of the bar is first operatedupon by the tools of the disk 10, and then the other side is operatedupon by the tools of the disk 20. These tools operate only during theirdownward travel, and the shafts 1-2 are inclined slightly in ahorizontal plane so that as the tools are traveling up they will clearthe bar. Supports 6, 6 one of which is adjustable are provided oppositethe point where the cutting takes place to prevent the bar fromspringing away from the tool.

Vertically arranged feed rolls 11, 12, are provided, one of which 12 ismounted in fixed bearings, the other roll 11 being adjustable toward oraway from the fixed roll in order to accommodate bars of varyingthickness. This adjustable roll 11 is held up in position by thecompression spring 13 and the force which it exerts can be varied bymeans of the threaded stem 15 having a hand-wheel 16. Its driving shaftis preferably sectional and has a universal joint so as to permit of anyslight lateral movement of the roll which may be necessary. At theirupper ends the shafts are supported in a frame f and carry worm-wheels17 which are engaged by a worm-pinion 18. As many pair of feed rolls areto be used as may be desirable or necessary. As these bars vary slightlyin thickness the shafts 1, 2, which carry the disks 10, 20, are providedwith means for moving them lengthwise through their bearings, in orderto correctly position the operating tools so that they will take aproper cut. The method of securing this adjustment which is illustratedcomprises a threaded stem 21 and a hand wheel 22 mounted in a stationarypart of the bearing and engaging the shaft.

There is thus provided a continuously opcrating sealping machine whichacts upon both sides of the bar simultaneously but at different points.The cutting tools while they are performing their work move in a curvedpath transversely of the bar. The chips drop down through the bed of themachine as soon as they are formed so that they do not further interferewith the operation of the cutting tools.

We claim 1. In a machine of the character described, a frame, alongitudinal track therethrough on which a bar of stock travels on edgethrough the machine, a set of bearings arranged in alinement on oppositesides of said track, a shaft supported in said bearings, a tool-carryingdisk secured to the shaft at one side of said track, metal scalpingtools projecting from one of the flat faces of said disk toward thetrack means for adjusting said disk to bring said tools into operativerelation with one side of a piece of stock as it travels along saidtrack, a second set of bearings located beyond the first set andarranged in alinement on opposite sides of the track, a shaft supportedin said bearings, a tool-carrying disk mounted on the shaft at theopposite side of the track from the first mentioned disk, metal scalpingtools projecting from one of the flat faces of said disk, means foradjusting the disk to bring said tools into operative relation with thestock as it moves on the track, means for driving said shafts, feedrolls engaging the stock to cause it to move through the machine, andabutments for the stock arranged opposite the tO Ol CaI'IfYiIIg, disks.7

2, In a machine of the character described, a frame, a track extendingacross said frame and along which a bar of'sto'ck is moved on edgethrough the machine, pairs of alined bearings, one pair in advance ofanother, the members of each pair being mounted on opposite sides ofsaid track, shafts supported in the bearings andextending across saidtrack, tool-carrying disks mounted on said shafts on opposite sides ofthe track, metal scalping tools projecting from one of the flat faces ofsaid disks and adapted to act upon the sides of the bar, means foradjusting said disks to- Ward and away'from the bar, abutments for thebar opposite each head, vertically arranged feed rolls mounted onopposite sides of the bar, the feed rolls on one side of the bar beingadjustable toward and away from the track. 7

'3. In a metal-Working'machine, the com-, bination With themachine frameprovided with a track for the passage of "a bar of stock, of rotarytool-holding disks arranged at opposite sides of the stock but out ofalinement With one another, and provided With metal scalping toolsadapted to 0perate simultaneously on both sides of the stock atnon-opposite points, the flat faces of said disks being approximatelyparallel ith the sides of the stock, a bearing back of each disk,shaftsto Which said disks are secured, supported at their rear ends insaid bearings, the forward ends of said shafts projecting beyond theflat faces of said disks, and bearings for the forward end of each shaftat the opposite side of the stock fromits disk.

l. In a metal-Working machine, the combination With a machlne frameprovided With a track for the passage of a bar of stock, of non-alinedrotary tool-holding disks arranged on opposite'sid'es of the track andprovided With metal scalping tools adaptedto operate simultaneously onboth sides ofthe stock at non-opposite points, shafts supporting saiddisks, and bearings for said shafts located at opposite sides of thecutting planes of the tools.
